There is no greater darling stock on the ASX than Cochlear, the fabulous Australian success story which has brought hearing to more than 250,000 profoundly deaf people globally through the bionic ear technology which was developed by Professor Graeme Clark at Melbourne University in the 1970s.

And for investors who paid just $2.50 a share when the panic-stricken Pacific Dunlop floated the business in 1994, Cochlear has been a magnificent investment, jumping another 50c to $72.32 in morning trade today.
